Hibernate提供错误错误为“当'hibernate.dialect'未设置时，对DialectResolutionInfo的访问不能为空'当没有互联网连接时 [英] Hibernate gives error error as "Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set" when there is no internet connection
问题描述
当'hibernate.dialect'未设置时，对DialectResolutionInfo的访问不能为空
错误。我认为我的应用程序在运行时试图访问互联网连接。我得到的详细错误如下： -

SessionFactory sessionFactory = configuration.buildSessionFactory（serviceRegistry）;
return sessionFactory;
}
catch（Throwable ex）{

抛出新的ExceptionInInitializerError（ex）;

我想解决这个问题因为互联网连接不可能始终可用。谢谢
要使用hibernate脱机，您必须在xml映射和配置文件中更改您的dtd。确保hibernate jar在你的类路径中
pre $ 用于xml映射文件
<！DOCTYPE hibernate-mapping SYSTEM
classpath ：//org/hibernate/hibernate-mapping-3.0.dtd>
用于配置文件：
<！DOCTYPE hibernate-configuration SYSTEM
classpath：//org/hibernate/hibernate-configuration-3.0.dtd>

I want to fix this issue because internet connectivity cannot be always available. Thank you
to use hibernate offline you will have to change your dtd in your xml mapping and configuration files.make sure hibernate jar is in your classpath
for xml mapping file
<!DOCTYPE hibernate-mapping SYSTEM
"classpath://org/hibernate/hibernate-mapping-3.0.dtd">
for configuration file :
<!DOCTYPE hibernate-configuration SYSTEM
"classpath://org/hibernate/hibernate-configuration-3.0.dtd">

这篇关于Hibernate提供错误错误为“当'hibernate.dialect'未设置时，对DialectResolutionInfo的访问不能为空'当没有互联网连接时的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
